Found an abandoned vintage car, how can I claim it.

[The Modfather]

So I do urbexing and found a nice little find in the middle of nowhere, the owner of the property went crazy and was sectioned years ago. He since then has passed away with no relatives or friends. The house and car have been abandoned since the 90s and he passed away in the early 2000s. Would it just be as simple as towing her away and applying for the logbook?
